How to get filter to redirect to another action?

Question

RedirectToAction is protected, and we can use it only inside actions. But if I want to redirect in a filter?

public class IsGuestAttribute: Acti         


        

Answer 1

Security/Authorization/Authentication Filters should use the AuthorizeAttribute and IAuthorizationFilter.

public class IsGuestAttribute: AuthorizeAttribute, IAuthorizationFilter
{
    public void OnResultExecuted(ResultExecutedContext filterContext)
    {
    }
    public void OnActionExecuting(ActionExecutingContext filterContext)
    {
        if (!Ctx.User.IsGuest) 
        {
            filterContext.Result = new RedirectToRouteResult(
                new RouteValueDictionary 
                { 
                    { "controller", "Home" }, 
                    { "action", "Index" } 
                });
        }
    }
}
